A 12.5 inch touch ultrabook with a Core i7-4600U processor, 8GB DDR3 memory, 256GB SSD and Windows 7 Professional
The Lenovo ThinkPad X240 is a 12.5" business ultrabook built for mobile professionals who need a durable, touch-enabled Windows 7 Pro machine. It combines an Intel Core i7-4600U processor with 8GB DDR3 RAM and a 256GB SSD in a carbon-fibre reinforced chassis tested to MIL-SPEC standards for pressure, humidity, vibration and temperature extremes. A fingerprint reader and backlit keyboard support secure, low-light productivity on the move.
The dual-core i7-4600U reaches up to 3.3 GHz to handle typical office multitasking, web sessions and video conferencing without slowing down during extended work periods. The 256GB solid-state drive keeps application launches and file access responsive when the system is under continuous use. 8GB of DDR3 memory provides enough headroom for multiple browser tabs and business applications running simultaneously without excessive paging.
MIL-SPEC testing at 15000 ft low pressure and temperature shock validates the cooling design for stable operation in varied environments. The ultrabook's lightweight construction and efficient U-series processor help maintain low fan noise during typical productivity workloads. Bluetooth 4.0 connectivity supports wireless peripherals without a noticeable impact on battery runtime during normal daily use.

The i7-4600U is a 15 W ultra-low-voltage chip, so the fan stays quiet during typical office work and only spins up under sustained heavy load; the carbon-fibre roll cage helps spread heat without becoming uncomfortable.
It provides two USB ports, a headphone/microphone combo jack and Bluetooth 4.0; you will need any USB peripherals, a wired headset or Bluetooth audio device, and a compatible AC adapter for charging.
The system uses DDR3 memory, so existing DDR3 SODIMM sticks can be added or swapped as long as they match the required voltage and speed for this platform.
